Ever since I bought the car ( 01 base) used at 90 k, I have been having this squeak sound coming from the suspension or the trunk I can not tell. It sounded like springs when u press it and let go. I took it to many shops but could not duplicate the problem, asked them to do a complete check on suspension system (ball joints, tie rod ends and any moving parts) and the trunk but everything checked out good. Followed the instruction on the web to take out the back seat and put foaming pads on every screws/nuts and tighten it. But the noise is still there.

Does any of you guys have any idea on what else I should check? Kinda of running out of ideas.........thought it may be coming from the chasis but don't know where to start? It does this most often when I am straight roads that have up and downs like twisty mountain road etc...thanks for any suggestions

I have the exact same noise coming from the same place. It has made the noise all 3 years I have owned the car but only when it is below about 50 degrees out. My guess is the suspension bushings as they are in place at every moving point on the suspension. My advice would be to get the energy suspension master bushing set. It runs about $230 but it replaces every suspension bushing you have and will tighten up the car greatly. That is my plan at least.
